ELECTROCONDUCTIVE BRUSH AND COPYING DEVICE FOR ELECTROPHOTOGRAPHY

摘要

An electroconductive brush which comprises a base fabric and a mixed fiber from a polyethylene terephthalate fiber and a nylon-66 fiber which is used for raising the base fabric through pile flocking, wherein the polyethylene terephthalate fiber and/or the nylon-66 fiber has a volume resistivity of 100 to 106 Ω . cm. The electroconductive brush exhibits improved performance capabilities and can be suitably used as a cleaning brush in a color copier which uses a color toner being finer than a conventional toner.
